TECHNICAL FIELD

BACKGROUND OF THE INVENTION

Most of existing hair curlers will have an exposed round rod heating element. In use, the hair is wound on the heating member for heating so that the hair is deformed and shaped in accordance with the shape of the heating member, thereby increasing the curl of the hair. The basic principle of a hair curler is: hair is mainly composed of protein, protein structure of the skeleton determines the shape of the hair; proteins have chemical bonds, such as disulfide bonds, hydrogen bonds and salt bonds, etc.; these chemical bonds are used to maintain the structure and shape of the hair. The straight hair is winded on the heating member. The heat of the heating member causes the hair to expand and open the chemical bonds in the protein to make the straight hair in a changeable state. At this point, once the straight hair is wrapped around the surface, the straight hair will be curled, and the curled hair is formed; when the curled hair is cooled, the chemical bonds in the hair protein will be rebuilt to keep the hair in a curled state. However, the existing hair curler has the following disadvantages: 1) high temperature will damage the hair, making the hair lose water; in order to improve the curling efficiency of the curlers, the operating temperature of the existing heating members of the curlers is generally up to 200° C.; when the hair touches the heating member for a long time, the hair will be seriously damaged; 2) At the same time, since the heat member is exposed, the user's hand, hair and face may be burned.

The main body 1 is a main part for being wound by hair and curling the hair. Preferably, in the present embodiment, the main body 1 is in a shape of a round rod. Of course, the main body 1 can also be in a shape of a dumbbell etc.

Further, referring to FIG. 1 and FIG. 2, a first internal space 4 is formed inside the main body 1. The main body 1 comprises a first proximal end 2 and a first distal end 3. In the present embodiment, the two ends of the main body 1 are the first proximal end 2 and the first distal end 3 respectively.

A first elongated slot 6 communicated with the first internal space 4 is formed on the first proximal end 2. Referring to FIG. 1 and FIG. 2, in the present embodiment, a first opening 8 of the first elongated slot 6 is formed on the first proximal end 2. In this way, the hair 33 can be easily put into the first elongated slot 6. Of course, the first opening 8 of the first elongated slot 6 can be formed on the side wall of the main body 1.

Further, referring to FIG. 1 and FIG. 2, the hair curler further comprises a first movable arm 7 movably disposed in the first internal space 4. A heating member for heating hair 33 is disposed on a slot wall of the first elongated slot 6 and/or the first movable arm 7.

Specifically, referring to FIG. 1, a connecting member is further formed on the main body 1. The connecting member comprises a movable mechanical structure, and the movable mechanical structure is a hinge structure 13. The first movable arm 7 is connected with the main body 1 through the hinge structure 13. In the present embodiment, the connecting member is disposed in the first internal space 4.

Specifically, in the present embodiment, referring to FIG. 1, the first elongated slot 6 extends from the first opening 8 to the first distal end 3, a bottom 9 is formed at an adjacent first proximal end of the first elongated slot 6 close to the first distal end 3; the hinge structure 13 is disposed between the bottom 9 and the first distal end 3; an axis of the hinge structure 13 is perpendicular to an extending direction of the first elongated slot 6; the first movable arm 7 is pivoted with the axis of the hinge structure 13 and forms a clip with the slot wall of the first elongated slot 6. The clip is for holding the hair 33.

Further, in the present embodiment, the heating member comprises a heating surface 12 disposed on the first movable arm 7 and a heating element 28 which is connected on the heating surface 12 and is used for heating the heating surface 12. A side wall of the main body 1 at the first proximal end 2 is a main body outer wall 5 for cooling the hair 33.

When the heated hair 33 is cooled down by the main body outer wall 5, the shape of the cooled hair 33 is fixed. In general, when the heating member is working, the temperature of the heating surface 12 is higher than the temperature of the main body outer wall 5; when the temperature of the heating surface 12 is higher than 180° C., the temperature of the main body outer wall 5 is at least 90° C. lower than the temperature of the heating surface 12, or the temperature of the main body outer wall 5 is lower than 50% of the temperature of the heating surface 12. Thus, to make the hair 33 curled, the main body outer wall 5 has a curved surface 27, as shown in FIG. 7.

Further, in the present embodiment, referring to FIG. 1, to prevent the first movable arm 7 and the slot wall of the first elongated slot 6 from holding the hair 33 for a long time, which will cause the hair 33 to be overheated to be burned, the minimum distance between the slot wall of the first elongated slot 6 and the first movable arm 7 is at least 0.5 mm. Here, in general, an angle is formed between the slot wall of the first elongated slot 6 and the first movable arm 7, as shown in FIG. 5. When the slot wall of the first elongated slot 6 and the first movable arm 7 close to each other, the minimum distance between the first elongated slot 6 and the first movable arm 7 is formed, as shown in FIG. 6. In this way, the hair 33 will be not over clamped.

Further, referring to FIG. 1 and FIG. 2, the hinge structure 13 further comprises a button 18. The button 18 is connected with the axis of the hinge structure through a connecting rod 181.

When using it, the portion of the hair 33 closing to the hair root 22 is put into the first elongated slot 6 to contact the heating surface 12, as shown in FIG. 8. Then the main body 1 is rotated to make the hair 33 wound on the main body outer wall 5, as shown in FIG. 9. Next, the hair 33 contacting the heating surface 12 is heated by the heating surface 12, and the main body 1 is moved in the direction of the hair trip 23, as shown in FIG. 9 to FIG. 11. In this way, after separating from the first elongated slot 6, the portion of the hair 33 heated by the heating member contacts with the main body outer wall 5 to be cooled down to form a curled portion 24; an uncurled portion 25 of the hair 33 continues to be put into the first elongated slot 6 to contact the heating surface 12.

The principle of the above-mentioned use method is shown in FIG. 13-FIG. 18. Before the hair 33 is heated, the structure of the hair 33 is shown in FIG. 14 and FIG. 15. Amino acids in proteins are linked by the hydrogen bond 32. When the hair 33 is put into the first elongated slot 6 and is heated by the heating surface 12, in the first part 29 of the hair 33, the hydrogen bond 32 in the protein is opened, as shown in FIG. 16. When the second part 30 of the hair 33 which leaves the first elongated slot 6 contacts the main body outer wall 5, the second part 30 is curled, as shown in FIG. 17. The hydrogen bond of the protein in the third part 31 of the hair 33 which leans to the main body outer wall 5 and has been cooled is reconstructed, thus making the shape of the third part 31 fixed, as shown in FIG. 18.
